Orbital Hybridization-Induced Ising-Type Superconductivity in a Confined Gallium Layer
Hemian Yi, Yunzhe Liu, Chengye Dong +24
In low-dimensional superconductors, the interplay between quantum confinement and interfacial hybridization effects can reshape Cooper pair wavefunctions and induce novel forms of…
Controlling nanothread backbone structure through precursor design
Andrew Reynoso, Bohan Xu, Vincent H. Crespi
Nanothreads are 1D carbon-based nanomaterials produced by pressure-induced polymerization of multiply unsaturated (and typically aromatic) precursors with multiple bonds between ad…
Field-tunable interactions and frustration in underlayer-mediated artificial spin ice
Susan Kempinger, Yu-Sheng Huang, Paul Lammert +5
Artificial spin ice systems have opened experimental windows into a range of model magnetic systems through the control of interactions among nanomagnet moments. This control has p…
Imaging the stochastic microstructure and dynamic development of correlations in perpendicular artificial spin ice
Susan Kempinger, Robert D. Fraleigh, Paul Lammert +4
We use spatially resolved magneto-optical Kerr microscopy to track the complete microstates of arrays of perpendicular anisotropy nanomagnets during magnetization hysteresis cycles…
Nonlinear dark-field imaging of 1D defects in monolayer dichalcogenides
Bruno R. Carvalho, Yuanxi Wang, Kazunori Fujisawa +10
Extended defects with one dimensionality smaller than that of the host, such as 2D grain boundaries in 3D materials or 1D grain boundaries in 2D materials, can be particularly dama…
Strong exciton regulation of Raman scattering in monolayer dichalcogenides
Yuanxi Wang, Bruno R. Carvalho, Vincent H. Crespi
The weakly screened electron-hole interactions in an atomically thin semiconductor not only downshift its excitation spectrum from a quasiparticle one, but also redistribute excita…
